Announcing the Developer Program Mainnet Season 4 Winners

Zama announced the three winners of its Developer Program Mainnet Season 4, which challenged builders to create functional confidential versions of PoolTogether-style no-loss prize savings pools using the Zama Protocol and fully homomorphic encryption. The projects, SaveTogether by @Himess__, CachePot by @yanyuan888, and confipool by @realchriswilder, were deployed on Sepolia and open-sourced, with each allowing users to deposit into shared pools, retain withdrawable principal, and receive yield-based prize distributions while keeping deposits, balances, odds, and winnings encrypted. Their designs preserved publicly verifiable onchain draws while seeking to prevent the privacy disclosures inherent in conventional public prize pools, including revealing participants’ stakes and prize claims. Zama noted that the community projects are unaudited and encouraged users to assess risks before connecting wallets, while presenting the submissions as demonstrations of how confidential applications could support more private onchain financial products; the program’s next season will focus on confidential gaming.
